Identification of a Stochastic Dynamic Model for Aircraft Flight Attitude Based on Measured Data
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 Stochastic disturbances are everywhere. The influence of stochastic factors on the modeling and simulation of aircraft flight dynamics should be considered. Therefore, a stochastic differential equation for aircraft flight attitude is modeled based on the traditional one in this paper.

Lift Augmentation on a Tiltrotor Wing Using the Combination of Vortex Generators and Gurney’s Flap
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 Recently, flow control using vortex generators (VGs) and a Gurney flap (GF) has received considerable attention, but independently. The purpose of this study is to perform a numerical investigation into the lift augmentation effects of a tiltrotor wing with the combination of VGs and GF.

Lift Enhancement of Tiltrotor Wing Using a Gurney Flap
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 A numerical investigation was undertaken to explore the lift‐enhancing characteristics of the Gurney flap on a tiltrotor wing. The heights of Gurney flaps range from 1 to 4% wing chord lengths. The Navier‐Stokes equations with the Spalart‐Allmaras turbulence model were solved to simulate the flow structure around the Gurney flap.
